LUBRICATOR.

Specification of Letters Patent.

Patented May 27, 1913.

Application tiled October 15, 1912. Serial No. 725,85.

To @ZZ whom t may concern Be it known that I, OLoF GHLssoir, a subjectof the King of Sweden, and resident of Skogsgatan 3, Sdertelje, in theKingdom of Sweden, have invented certain new and useful Improvements inLubricators, of which the following is a speciication, reference beinghad therein to the accompanying drawing.

This invention relates to improvements in lubricatcrs of that class,adapted especially for motors, in which a reciprocating piston or thelike forces the oil through a conduit to the part or parts to belubricated. In one and the same lubricator or a so called centrallubricator generally a plurality of pumps are provided, corresponding tothe conduits respectively.

The invention consists in the oil being fed to the pistons by means ofwicks and pipes or the like. Through the said arrangement the advantagesare gained, that no superfluous quantity oi oil is fed to the piston,which at tree or full admission of oil generally transmits more oil thanis normally necessary, and that, if the wick is not raised, such aquantity of oil is accumulated in the conduit, while the motor is at astandstill, that no extra. quantity of oil must be supplied to thebearing or the part to be lubricated, as the motor is started. Moreover,no dirt can accompany the oil to the pump and the bearing etc.

The invention also relates to simple means for actuating the pistons.

Figure 1 in the accompanying drawing is a transverse section of theapparatus on the line a, o of Fig. 2. Fig. 2 is a longitudinal sectionof the apparatus on the line c, d of Fig. 1. Fig. 3 is a plan view ofthe apparatus. Fig. 4 shows a detail and Fig. 5 shows a modification.

From the oil box 1 several conduits 2, 2 extend, into which the oil isintroduced through the valves 3 by the pistons 4. The oil passes intothe chamber, located under the piston, from the pipe 6 through thechannel 5. In the said pipe 6 a wick 7 is located, which extendsdownward into the oil provided in the box outside the pipe.Consequently, the oil is fed continually to the piston by the said wick.It the pistons are at a standstill, a small quantity of oil is,

meanwhile, accumulated in the bottom part of the pipe and in the chamberlocated under the piston, if elevated, which oil is forced to itsdestination as soon as the lubricator is started.

The pistons 4 are actuated by a cross beam 9 and a shaft 10, whichlatter has a crank pin 11 eccentric or the like, embraced by the beam.The said beam is square in cross section and is embraced by the pistons,which in their top ends are provided with a lateral recess 12, Fig. 4,in which the beam lits. The bearing 13 of the shaft 10 is xed to theouter side of the box 1 by means of screw bolts and nuts 14, so that itcan easily be removed. After the bearing has been disengaged, the shaftand the bearing can be removed from the box, thus rendering free thecross beam 9, which can then be disengaged Jfrom the pistons by beingmoved laterally. In this manner also the pistons become free and can belifted or removed from the cylinders separately.

The modification shown in Fig. 5 consists in the crank pin 11 beingprovided with a block 15, which is slid on the said pin and can bereciprocated in a slot 16 provided in the cro-ss-beam 9 and extendinglongitudinally of the same. Owing to the said arrangement the beam doesnot slide forward and backward with relation to the pistons.

Having now described my invention,what I claim as new and desire tosecure by Letters Patent is:

1. In a lubricator, the combination with a plurality of pistons andtheir cylinders and means for directing oil to the places to belubricated, of upright tubes one for each piston and its cylinder andlocated to one side of the piston cylinder, conduits for leading oilfrom the said tubes to the piston cylinders, an oil reservoir, a wick ineach tube extending into the oil reservoir for supplying the tubes withoil, a cross beam common to the pistons connect-ing them one withanother and means for reciprocating the cross beam and hence thepistons.

2. In a lubricator, the combination with a plurality of pistons andtheir cylinders and means for directing oil to the places to belubricated, of upright tubes, one for each piston and its cylinder,conduits for leading oil from the said tubes to the piston cylin- InWitness whereof, I have hereunto signed my name in the presence of twosuhseribing Witnesses.
